O The citric acid cycle involves one or more redox reactions. O The citric acid cycle is part of cellular respiration.Your body makes NAD+ from two B vitamins, niacin and riboflavin. You need only tiny amounts of these vitamins. The U.S. Food and Drug Administration’s recommended dietary allowances are 20 mg daily for niacin and 1.7 mg daily for riboflavin. These amounts are thousands of times less than the amount of glucose your body needs each day to fuel its energy requirements. How many NAD+ molecules are needed for the breakdown of each glucose molecule? Why do you think your daily requirement for these substances is so small?The equation for cellular respiration is shown.
